Air Quality Update Jan 21, 2018

Posted on January 21st, 2018

Air quality is moderate in the upper Midwest today (Sunday Jan 21), with AQI values in the 50-100 region. A few spots are above 100 — and that is “unhealthy for sensitive groups.” Many locations are just below 100.

The moderate conditions cover most of Iowa, Wisconsin, and parts of Illinois, Michigan and southern Ontario. Both the US and Canadian forecast models show conditions IMPROVING throughout Sunday and improving more on Monday — due to the winter storm moving through the region (currently centered in Nebraska and moving northeast).
